SONY TC-K500R

Commentary

Cassette deck equipped with sound focus function.

Equipped with a sound auto-focus function, the deck itself senses not only the type of tape and the presence or absence of Dolby NR but also the peak level and high-frequency components of the source. Based on this information, the computer analyzes the optimum value and automatically sets the recording level taking advantage of the capabilities of the tape.

The head uses an LC-OFC wound laser amorphous head that takes advantage of the magnetic properties of amorphous magnetic alloys and employs an LC-OFC (linear crystalline oxygen-free copper) in the head winding of the original laser amorphous head. This reduces distortion due to capacitive reactances and reduces loss in the mid-range and high-range.

Equipped with the Dolby HX-PRO, the effective bias amount is controlled to the optimum value in 1/1000 second increments to prevent over-bias in the high-frequency range and improve linearity in the high-frequency range. This function works only during recording, so it is effective even when played on a deck without the Dolby HX-PRO.

Super-bias is adopted, and by shifting up the bias frequency greatly, the frequency difference with the music signal is expanded, and beat noise and intermodulation distortion due to interference between the bias frequency and the music signal are suppressed.

Equipped with bias fine tuning function, bias value can be finely adjusted.

Equipped with Dolby NR B-C type.

Vibration control material with large internal loss is adhered to the chassis, and further vibration control material is inserted in the joint part of each chassis to suppress unnecessary vibration of the case.

The power cable uses a φ 7.5 cap-tire OFC power cord with polarity indication.

Uses gold-plated input / output terminals with low contact resistance and little change over time such as rust and corrosion.

By using the included wireless remote control, you can record in sync without connecting a sync cord to a CD player supported by Sony's remote control.

Equipped with FL tube adoption linear electronic counter with subtraction function of minute and second display.

It is equipped with a wide range peak program meter that displays real-time peak values in the range of -40dB to + 8 dB and also has a peak hold function.

Equipped with a display ON/OFF switch, three modes can be selected : all lights, counter only, and all lights.

It is equipped with a pre-end winker function to let you know by flashing the counter number when the end of the tape is near during recording.

Equipped with an auto-fader function, you can fade in or out from the position where you press the auto-fade button.
In addition, you can also fade in by recording messages in conjunction with the timer.

It is equipped with a quick Oatley birth function that realizes quick action with almost no sound cut when reversing the tape.

Equipped with AMS (Automatic Music Sensor) function that can quickly find the beginning of the previous or next music.

Equipped with an auto tape selector that automatically detects whether the tape being used is type I (normal), II (high position), or IV (metal).

Equipped with an autoplay function that automatically starts playing after rewinding, and a memory play function that starts playing from the position reset to counter 0.

Timer recording and alarm clock playback are possible by combining the separately sold timer.

Equipped with a Rec Mute function with auto-space that automatically mutes for approximately 4 seconds.
